The statistics of 1930 urological operations performed at the Department of Urology, Osaka University Hospital in the 5 year period from 1972 to 1976 were made. They were compared with the proceeding statistics of two periods (1957～1966 and 1967～1971), and the recent trend of urological operations was investigated. 1. Operations upon the bladder and the prostate have increased and those on the urethra decreased compqring preceeding 5 years. 2.
